Thanks !

must have made a mistake. clang still aborts when compiling with -DNDEBUG :(

looks like a clang issue
changing free_edicts_count++; to free_edicts_count = free_edicts_count + 1;
( the same for free_list_count++ )
prevents the warning.

I'll enclose both lines with #pragma clang diagnostics for now
